Chamfering
- Thread starter RHarris
- Start date
Chamfering is done to revolver cylinders (i.e., the actual hole where each cartridge is inserted), at the back where the case rim sits. It is beveling of the sharp 90-degree angle.
The purpose is to facilitate insertion of cartridges into the cylinders. Some sharp-shouldered and hollowpoint ammo sometimes hangs up on the front edge of the cylinder, especially when using a speedloader. Chamfering breaks the edge and makes it easier to "funnel" the bullet noses into the chambers.
Brownell's sells a chamfering tool that works well. It is not too hard to use for one who is competant with hand tools.

However . . .
Chamfering will also marginally reduce the absolute strength of the cylinder. I am not suggesting that this makes any practical difference in virtually all cases, but with the hottest loads and expanded or extra-rounds cylinders, it might be worthy of consideration.
